Reaction Time Test: ReflexLab

How fast are your reflexes? Most people react in about 250 milliseconds. Some are faster. ReflexLab tells you exactly where you stand. THE BOARD RESETS EVERY MONDAY ReflexLab wipes its leaderboards every Monday. Four boards, one per mode, a countdown on each. Last week is gone and this week is open. You could win it. FOUR TESTS, ONE LAB CLASSIC · reaction time test Wait for the signal. Tap the instant it turns blue. Five rounds, and your fastest is the score. Tap early and the round is lost. RAPID FIRE · tap speed test Three seconds. As many taps as your finger can land. STROOP · a real Stroop test The word GREEN, printed in red ink. Tap only when word and ink agree. Fifteen seconds of your brain arguing with itself. PHANTOM RING · precision timing A ring flashes, then grows toward the mark. Tap the moment they meet. Scored in pixels — land within 8 and it's rated PERFECT. DAILY CHALLENGE One attempt a day. Everyone gets the same sequence, so the scores actually compare. Keep the streak alive and fill the month's calendar. MEASURED, NOT GUESSED Every session is timed to the millisecond and saved on your device. The Performance chart answers one question: are you getting faster? The Activity grid shows every day you trained. Reaction training only counts when the number moves. SHARE THE NUMBER Every result exports as a clean score card. Send it to the friend who swears they're faster.
